Cosumnes River Flow Sample Clauses

Cosumnes River Flow. The Program’s in-lieu groundwater recharge activities will improve groundwater levels adjacent to the Cosumnes River and will reduce water losses from the stream to the aquifer and/or increase water gains from the aquifer to the stream. At the time of contract execution, Program groundwater modeling estimates an average annual streamflow improvement of around 13,000 acre-feet resulting in an average of 31 additional days of flows at or above 20 cubic-feet per second (cfs) as modeled at Twin Cities Bridge, starting Program Year 20 and maintained throughout the term of this Contract, when compared to without-Program conditions1. The model estimates that about 11 of these additional days will occur, on average, within the October to December migration window for adult salmonids. These flows will begin accruing in the first few years of Program operations and will be achieved approximately 20 years after Program implementation, as demonstrated through higher streamflows and groundwater elevations simulated at Twin Cities Bridge and at a shallow aquifer monitoring well located near the Cosumnes River and within the Program Area, respectively.

Cosumnes River Flow. The Program’s in-lieu groundwater recharge of 41,250 acre-feet per year on average will improve groundwater levels adjacent to the Cosumnes River and will reduce water losses from the stream to the aquifer and/or increase water gains from the aquifer to the stream. Groundwater models estimate that streamflow will increase by an average of approximately 13,000 acre-feet per year and provide an average of 31 additional days per year of flows in the Cosumnes River at or above 20 cubic feet per second (cfs). These additional flows are expected to benefit aquatic organisms including fall-run Chinook salmon. The Department finds that Cosumnes River Flow benefit constitutes an ecosystem improvement that meets the requirements of Water Code section 79750 et seq.
